although north korea is working on the technology. everyone i've spoken to the pentagon say they're not close to perfecting it. alaska is about 3500 miles away from north korea, california between 5,000 and 6,000 miles. they haven't come close to testing a rocket that's gone nearly that far. they've tested this type of technology about three times. in 2006, the rocket flew about 40 seconds and exploded. in 2009, they tried to put a sat white into orbit, but that broke up over the sea well short of what they had sbeintended. and then six months ago, they tested similar technology again. it flew but again broke up over the sea. so they've had three failures it took the united states about 24 launches to perfect this technology, a third of which failed. so it's not easy to do. and north korea, although they seam to be improving, they're not close to what they just claimed. >> as you mentioned, back in april they had the test that failed. south korea just approved to increase their range to the northern peninsula. how much of this is abou
